Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a remote supervisory system that can surely confirm in which direction a supervisory camera supervises an object even when a supervised image is dark in the case of supervision at night. SOLUTION: An image memory 32 stores an ominidirectional image photographed by the supervisory camera 11 in advance at a daytime as a still picture. When an operator operates an operation device 23 to give an instruction of image composition at the supervision at night, a control section 35 allows a still picture output section 33 to read the still picture synchronously with a direction and a field angle supervised by the supervisory camera 11 at present from the stored picture in the image memory 32 and to output the still picture to an image output section 34 on the basis of a swing angle and the field angle of the supervisory camera 11. The image output section 34 composites the current picture by the supervisory camera 11 with the still picture outputted from the image memory 32 and outputs the composed image to a monitor 22.  Thus, a supervisory person can confirm in which direction the supervisory camera 11 supervises the object at present by using the daytime picture with the same field angle.
